SVG Fundamentals
A static SVG canvas demonstrates fundamental vector shapes: a yellow circle with a navy outline, a small red rectangle, a vertical navy line, and a gray polyline. The example uses plain SVG elements (`circle`, `rect`, `line`, `path`) directly within an HTML document, with no JavaScript library or data source. It highlights basic geometry, positioning, fills, strokes, and path syntax, serving as a minimal reference for SVG markup in a browser context.
